ANTENNA.

Application filed February 9, 1925.

This invention relates to a new and improved form of radio antenna. Anobject of the invention is to provide a fabric in which an antennaelement is woven so that the antenna can be eiiiciently supported andincorporated with the material, which can be used incidentally in anornamental manner in connection with the interior of a house.

Another object concerns the provision of means whereby a considerablelength of antenna can be properly installed on a short length of a givensupport.

A further object concerns the provision of a suitable support for anantenna which can be incorporated with the decorations of a house, beout of the way, not particularly expensive, and harmonize with thefurnishings.

The invent on is illustrated in the drawings, of which- Figure 1 is aplan view of a strip of braid in which an antenna is incorporated;

Fig. 2 is a section therethrough; and

Fig. 3 is a plan view of a portion of a rope or cord into which theantenna is woven or twisted.

The form of the invention shown in the drawings is a preferred form,although it is understood that modifications in the construction andarrangement of the parts and in the character of the materials used maybe adopted without departing from the spirit of the invention as setforth in the appended claims.

In its general aspect the idea comprises, broadly, the provision of azigzag antenna.

More specifically, the invention includes the idea of suitablyincorporating a zigzag antenna on a desired base.

More specifically, the invention comprises weaving a braid or tape witha zigzag antenna element woven therein.

Still more specifically, the invention includes the idea of weaving ortwisting into a rope or cord an antenna element, preferably in a spiralfashion, so that a great lengthof antenna element can be incorporated ina given length of cord or rope.

In the preferred form of the. invention, as

Serial No. 8,034.

shown in Fig. 1, I provide a braid 10 into which, preferably during theprocess of man ufacture, a conductive antennaelement 11 is woven in azigzag fashion. By thus manufacturing the braid or other fabric, aconsiderable length of antenna element can be woven into a given lengthof braid or into a given length of sheet material.

As shown in Fig. 3, a rope or cord 12 is suitably woven, braided ortwisted, and into this is incorporated a spiral conductor element 13which acts as an antenna.

The particular manner in which the antenna element is incorporated inthe fabric is not essentially important.

It is to be clearly understood that the fabric or sheet of material intowhich the antenna wire is woven may itself be made of insulated metallicwires, each of which can serve as an element in the antena. In otherwords, the braid, tape, sheet of material or cord, can be made ofinsulated antenna wires entirely. This sort of construction will containa considerable number of zigzag antenna, which will have a considerablygreater capacity than a fabric containing only one or two wiressupported therein. It will also be suitable for both outside and insideantenna. In other words, the support or mounting for any particularantenna wire may be a plurality of other antenna wires with which it isincorporated.

What I claim is 1. An antena which comprises a flat sheet of fabriccomprising a plurality of braids or strands laid parallel to each otherand of insulating material and a conductor woven progressively forwardin a zigzag manner across the sheet alternately between the strands ofthe sheet.

2. An antenna comprising a narrow sheet or tape of insulating material,and a flexible conductor interwoven in said sheet extending alternatelyacross the sheet longitudinally thereof, and lying flat whereby toincrease the capacity of said conductor in collecting radiant energy.
